What is an ETSO authorization?

An ETSOA shows that a part or appliance

complies with a minimum performance standard

The ETSOA is optional, installation approval is

anyway required

Introduction on IMA - History

IMA stands for Integrated Modular Avionics

Modular & incremental development of the aircraft function

FAA released TSO-C153 in June 2002

ED-124/DO-297 was released in November 2005

Containing letter of acceptance (FAA system)

Breakdown of tasks/split in incremental steps

Requirements on the modularity (incl. Partitioning)

During number of yearsEU industry expressed the need of an IMA ETSO

2012 : EASA starts to work on ETSO-2C153, consideringthe EASA system …and the IMA experience of 15 years

April 2016 IMA ETSO-2C153 - Avionics Workshop 4

The 2C153 Concept – in EASA system

ETSO approval independent from the aircraft installation

there is no requirement that an installation process is concurrent to the ETSO process

The clear EASA intent to keep the two processes interoperable but independent

No approval letter concept at EASA approval of equipment (ETSOA) or product (TC, STC)

As a conclusion : EASA intended to have

defined perimeter of the IMA platform/modules,

+ MPS on modular aspects/functions

this is a step forward to FAA TSO-C153 (not incompatible),

with Minimum Performance StandardApril 2016 IMA ETSO-2C153 - Avionics Workshop 5

IMA ETSO-2C153 - Avionics Workshop

Publication is imminent !

ETSO-2C153, different from FAA TSO-C153

14 years later, developed from this experience

ETSO-2C153 is different from FAA TSO-C153 :

Defines classes and Minimum Performances for eachclass

Include Health Monitoring

Requires to characterise the platform/modules to the user & verify

Use of Ed-124/DO-297, task 1

Environmental qualification adapted for modules

User Data (User Guide) to identify/document the requirements/constraints to be respected by User


ETSO Validation aspects

ETSO-2C153 is different from FAA TSO-C153

But not incompatible with FAA TSO-C153

FAA TSO-C153 is not included in the ReciprocalAcceptance from TIP of Bilateral agreement EU-US

Additional Activities & Data Package for demonstrationof compliance to ETSO-2C153 MPS will be needed(requirements in each Appendix)

Incremental certification of IMA (from platform & modules up to aircraft)

RMT.0621

Subpart A

CS-ETSO

CS-23, CS-25, CS-27, CS-29…

On-going drafting of AMC 20-170

On going rulemaking task to develop AMC on IMA

Will cover requirements from Platform to the full integration in the aircraft

Will recognize ED-124/DO-297 tasks and associated objectives

Will cover the use of ETSO IMA based platforms

AMC 20-170 will replace the Draft Certification Memorandum published and used through CRI
